tested with tcrypt and automated filesystem tests.

Rename module from serpent.ko to serpent_generic.ko and add module alias. This
is to allow assembler implementation to autoload on 'modprobe serpent'. Also
add driver_name and priority for serpent cipher.

Thanks for the suggestion, the init() is replaced with

and fini () is replaced with &lt;algorithm name&gt;_mod_fini.

<title>[CRYPTO] api: Get rid of flags argument to setkey</title>

Now that the tfm is passed directly to setkey instead of the ctx, we no
longer need to pass the &amp;tfm-&gt;crt_flags pointer.

This patch also gets rid of a few unnecessary checks on the key length
for ciphers as the cipher layer guarantees that the key length is within
the bounds specified by the algorithm.

Rather than testing dia_setkey every time, this patch does it only once
during crypto_alloc_tfm.  The redundant check from crypto_digest_setkey
is also removed.

Up until now algorithms have been happy to get a context pointer since
they know everything that's in the tfm already (e.g., alignment, block
size).

However, once we have parameterised algorithms, such information will
be specific to each tfm.  So the algorithm API needs to be changed to
pass the tfm structure instead of the context pointer.

This patch is basically a text substitution.  The only tricky bit is
the assembly routines that need to get the context pointer offset
through asm-offsets.h.
